Tesla unveils new Dojo supercomputer so powerful it tripped the power grid
Tesla has unveiled its latest version of its Dojo supercomputer and it’s apparently so powerful that it tripped the power grid in Palo Alto.
Dojo is Tesla’s own custom supercomputer platform built from the ground up for AI machine learning and more specifically for video training using the video data coming from its fleet of vehicles.
The automaker already has a large NVIDIA GPU-based supercomputer that is one of the most powerful in the world, but the new Dojo custom-built computer is using chips and an entire infrastructure designed by Tesla.
The custom-built supercomputer is expected to elevate Tesla’s capacity to train neural nets using video data, which is critical to its computer vision technology powering its self-driving effort.
Last year, at Tesla’s AI Day, the company unveiled its Dojo supercomputer, but the company was still ramping up its effort at the time. It only had its first chip and training tiles, and it was still working on building a full Dojo cabinet and cluster or “Exapod.”
Now Tesla has unveiled the progress made with the Dojo program over the last year during its AI Day 2022 last night.
The company confirmed that it managed to go from a chip and tile to now a system tray and a full cabinet.
Tesla claims it can replace 6 GPU boxes with a single Dojo tile, which the company claims costs less than one GPU box. There are 6 of those tiles per tray.
Tesla says that a single tray is the equivalent of “3 to 4 fully-loaded supercomputer racks”.
The company is integrating its host interface directly on the system tray to create a big full host assembly:
Tesla can fit two of these system trays with host assembly into a single Dojo cabinet.
Here’s what the Dojo cabinet looks like closed and opened:
That’s pretty much where Tesla is right now as the automaker is still developing and testing the infrastructure needed to put a few cabinets together to create the first “Dojo Exapod”.
Bill Chang, Tesla’s Principal System Engineer for Dojo, said during
“We knew that we had to reexamine every aspect of the data center infrastructure in order to support our unprecedented cooling and power density.”
They had to develop their own high-powered cooling and power system to power the Dojo cabinets.
Chang said that Tesla tripped their local electric grid’s substation when testing the infrastructure earlier this year:
“Earlier this year, we started load testing our power and cooling infrastructure and we were able to push it over 2 MW before we tripped our substation and got a call from the city.”
Here’s how the Tesla Dojo Exapod looks like opened and closed:
Tesla released the main specs of a Dojo Exapod: 1.1 EFLOP, 1.3 TB SRAM, and 13 TB high-bandwidth DRAM.
The company used the event to try to recruit more talent, but it also shared that it is on schedule to have its full first cluster or Exapod, in Q1 2023.
It is currently planning to have 7 Dojo Exapods in Palo Alto.
Why does Tesla need to Dojo supercomputer?
It’s a fair question. Why is an automaker developing the world’s most powerful supercomputer? Well, Tesla would tell you that it’s not just an automaker, but a technology company developing products to accelerate the transition to a sustainable economy.
Musk said it makes sense to offer a Dojo as a service, perhaps to take on his buddy Jeff Bezos’s Amazon AWS and calling it a “service that you can use that’s available online where you can train your models way faster and for less money.”
But more specifically, Tesla needs Dojo to auto-label train videos from its fleet and train its neural nets to build its self-driving system.
Tesla realized that its approach to developing a self-driving system using neural nets training on millions of videos coming from its customer fleet requires a lot of computing power. and it decided to develop its own supercomputer to deliver that power.
That’s the short-term goal, but Tesla will have plenty of use for the supercomputer going forward as it has big ambitions to develop other artificial intelligence programs.

Slate Auto, a new EV startup backed by Jeff Bezos, has poached a key Tesla manufacturing leader to build its electric pickup truck factory in Indiana.
Napoleon Reyes is a US Marine from Indiana who got a degree in mechanical engineering from Purdue after leaving the force.
He then worked a few years at Subaru and Wabash before joining Tesla’s manufacturing team at the Fremont Factory in 2020.
There, he became part of the Model Y production ramp and was quickly promoted to lead the Model Y General Assembly in Fremont in 2022.
Reyes led Model Y GA, one of the most critical parts of vehicle manufacturing, for more than a year before being promoted again to lead new pilot processes at the factory.
Most recently, he led the launch of the general assembly line for the Model Y refresh.
The new engineering manager announced this week that he is leaving Tesla to join Slate:
A bit late on the post but after nearly 5 years working at Tesla in Fremont, I made the difficult decision to leave the Company and move closer to home with my family. It was an incredible experience being part of multiple line expansions and multiple Model Y program launches. Leading and managing the Model Y Refresh launch for GA in Fremont this year tested me professionally however we ultimately succeeded due to our amazing cross functional team collaboration. It’s been an absolute pleasure working with such great people, and I will forever be proud and thankful for everything we accomplished together.
I will be taking on a new role as Senior Manager, Plant Vehicle Engineering at Slate Auto in Warsaw, In.
Slate emerged from stealth mode earlier this year to unveil a new type of electric pickup truck featuring modular customization and an affordable price.
The company raised over $700 million through two rounds of investments from several different investors, including Jeff Bezos. It is currently raising more, which basically guarantees that it will be able to reach production.
The startup acquired a former printing plant in Warsaw, Indiana. It is currently converting to manufacture its electric pickup with a team from legacy automakers and also several former engineers and leaders from Tesla.
Rich Schmidt, an early Tesla manufacturing director, is the head of manufacturing.

Genesis is preparing to shake things up with its most luxurious SUV yet, the GV90. Thanks to a new patent filing, we are getting a detailed look at how its Rolls-Royce-style coach doors will work.
New patent reveals Genesis GV90 coach door system
When Genesis first unveiled the full-size SUV at the NY Auto Show last March, it wasn’t the stunning design or advanced tech that caught everyone’s attention. It was the coach doors.
Although we were worried it wouldn’t make it to the production model, like many concepts, the Genesis GV90 will be offered with coach doors.
The ultra-luxe electric SUV was first caught with coach doors earlier this year on a car carrier in South Korea. Just last month, the GV90 was spotted in California with a hinge at the rear to open the coach doors.
After several new patents were filed with the United States Patent and Trademark Office for new door latching devices, we are getting a sneak peek at how they are expected to work.
The patents, titled “Cinching Device For Door Latches in Vehicle,” and “Door Latch Device for Vehicles,” give a pretty detailed explanation of how the Genesis GV90’s coach doors will operate. The “Door Latch Device” uses a door striker on the lower side of the door, which is opened or closed by a hinge unit.
Unlike traditional doors, which use the B-pillar for support, the device is attached directly to the door itself, allowing for hinge-like movement.
The cinching device works in a similar way. It’s also attached to the door and part of the vehicle. However, unlike most of its kind, Genesis found a way to use a single cinching device to control multiple units. Again, the device is used for B-pillarless doors that swing open.
Genesis already said that B-pillarless coach doors are now feasible in production vehicles. The patent reveals a glimpse into how the luxury automaker could make it a reality.
Although the Genesis GV90 is expected to be offered with coach doors, they will likely not be standard. Other variants, with traditional door handles, have also been spotted testing in the US and South Korea.
Genesis is expected to launch the GV90 in mid-2026. It will be built at Hyundai’s Ulsan plant in South Korea. The flagship Genesis SUV is scheduled to debut on Hyundai’s new eM platform, which the company said will “provide 50% improvement in driving range.” It will also be loaded with the latest technology, software, connectivity, and Level 3 or higher autonomous driving capabilities.
